Product Overview

ADN8834 is a monolithic TEC controller with an integrated TEC controller. It has a linear power stage, a pulse-width modulation (PWM) power stage, and two zero-drift, rail-to-rail operational amplifiers. The linear controller works with the PWM driver to control the internal power MOSFETs in an H-bridge configuration. By measuring the thermal sensor feedback voltage and using the integrated operational amplifiers as a proportional integral differential (PID) compensator to condition the signal, this device drives current through a TEC to settle the temperature of a laser diode or a passive component attached to the TEC module to the programmed target temperature. It is widely used in application such as TEC temperature control, optical modules, optical fibre amplifiers, optical networking systems, instruments requiring TEC temperature control etc.
  • Patented high efficiency single inductor architecture
  • Integrated low RDSON MOSFETs for the TEC controller
  • TEC voltage and current operation monitoring
  • Independent TEC heating and cooling current limit settings
  • Programmable maximum TEC voltage, temperature lock indicator
  • 2MHz PWM driver switching frequency
  • External synchronization, capable of NTC or RTD thermal sensors
  • Two integrated, zero drift, rail-to-rail chopper amplifiers
  • Operating temperature is -40°C to +125°C
  • Package style is 25-ball WLCSP
